A cluster of ancient burial mounds built from the early 7th century to the late 9th century

The Akobo Kofun cluster is a collection of burial mounds built over approximately 300 years, spanning from the Asuka period to the Heian period. They are a type of burial mound called “Makki Kofun,” and are believed to be the graves of Emishi leaders who inhabited the region during that time.
A total of 125 circular burial mounds have been discovered so far, and currently, over 60 mounds are open for observation. Artifacts such as magatama beads, warabiteto iron swords, and arrowhead pottery can be viewed in the permanent exhibit at the Oirase Akobo Kofun Museum.
